Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121974, here are decompositions:

7 + 121967 = 121974
11 + 121963 = 121974
23 + 121951 = 121974
37 + 121937 = 121974
43 + 121931 = 121974
53 + 121921 = 121974
107 + 121867 = 121974
131 + 121843 = 121974

Showing the first eight; more decompositions exist.
